Access to strong electric field devices

Abstract

The invention belongs to the technical field of live working devices for high-voltage transmission lines, and in particular relates to a device for entering and exiting a strong electric field. Including traction system, operation system and protection system; traction system includes tractor, tumble block and lifting rope; operation system includes three-dimensional frame Ⅰ and plane frame Ⅱ, frame Ⅱ is set at the upper end of the rear side of frame Ⅰ, and the lower side of frame Ⅰ is set There is pedal Ⅰ, connecting piece Ⅰ is set on frame Ⅰ, pedal Ⅱ is set on the foldable left and right sides of frame Ⅰ, plane frame Ⅲ is foldable on the left and right sides of the upper end of frame Ⅰ, and the upper end of frame Ⅲ is buckled The detachable connection frame II; the hoisting rope is connected to the tractor, the bucket block and the connecting piece I in sequence, and the protective rope is connected to the connecting piece I and the locking block. The entry and exit strong electric field device can reduce the labor intensity of operators, expand the operation area, facilitate operations, ensure the safety of operators, and at the same time facilitate warehouse storage and road transportation.

Description

technical field [0001] The invention belongs to the technical field of live working devices for high-voltage transmission lines, and in particular relates to a device for entering and exiting a strong electric field. Background technique [0002] In the 110-220kV transmission line live overhaul operation, the equipotential operation method is one of the commonly used operation methods. Equipotential work refers to the work carried out when the operator wears a full set of shielding protective equipment, enters a strong electric field with the help of insulating tools such as an insulating ladder, and directly contacts the electrified body, which is at the same potential as the electrified body. Live maintenance of transmission lines such as repairing wires with live wires, replacing anti-vibration hammers with live power, and replacing the entire string of insulators with live power often requires equipotential work, and equipotential personnel need to use safe and reliable ...

AI Technical Summary

Problems solved by technology

[0004] The use of the above-mentioned strong electric field device will have the following problems: 1. When the wires that need live maintenance are too high, the equipotential personnel rely on manpower to climb the soft ladder to enter and exit the strong electric field, and the physical exertion is too large, which is easy to cause the physical condition when working in the strong electric field In the case of poor mental state, it is impossible to carry out work efficiently and attentively, thereby reducing work efficiency and work quality, and increasing safety risks; 2. Due to the limitation of the structure of the insulated ladder, the working area for equipotential personnel carrying out equipotential maintenance work at high altitude It is narrow and inconvenient to carry out actual work; 3. Equal potential personnel working at heights may lose backup protection due to human factors of ground electricians, resulting in high-altitude falling accidents, and the protection measures are not safe and reliable enough
